[TYPO3-mvc] Fluid checkbox - group from objectStorage

[Jonas Götze]

Hi list,

I have an Objectstorage and want to render the possible objects as 
checkboxes.
Fluid currently offers checkboxes for boolean and array-types 
(propertyValue). If its an array it appends [] to the name, so that it 
can be handled correctly by Extbase afterwards and also checks if the 
value should be checked already.
This should imho be the same if it is an object storage.

Somehow like that (in render-Method of CheckboxViewHelper):
elseif (get_class($propertyValue) ==  Tx_Extbase_Persistence_ObjectStorage){
				$checked = $propertyValue->contains($valueAttribute);
				$nameAttribute .= '[]';
			}

What do you think?
Should I otherwise convert my objectStorage to an array in the 
getProperty-Method to get it correctly working?

Regards
Jonas
